MSD distributor parts interchange question?

I have access to a 400 MSD Billet distributor etc. for real reasonable-like to good to pass up kinda deal.

I'm building a 440. I know you can go from a 440 to a 400 distributor.

Any good ideas on the 400 distributor and adapting it? I know it is shorter. I emailed MSD but have not heard anything.

I'm hoping I could buy a new shaft for $50 or something and use it.

Thank you for your thoughts.

I finally heard back from MSD. They will sell the shaft separately that will allow you to run a distributor in either an 440 or a 400. Apparently the body of the distributor is the same.

It is around $50 he said.

Maybe this will help someone else.

Take care!
